I bought a copy of Croc for about a week ago (wonderful game, a bit childish, but very fun and great Gfx!). Inside of it there was a label that said that i had to start the Saturns cd-player and then insert the cd to play the game. I did this and it ran perfectly, but i wondered why, so i tried starting it as usual, and then all caracters lacked loads of polygons and some things were not visible at all. What i wonder is why? Does it uses another Co-processor for 3d calculating, like Grandia? I mean, Croc looks fantastic. Also, are there any other Saturn games that uses this teknique?
